As someone who's experienced life prior to the internet, it's not that one can't live without social media but it does affect how easy it is to organize things when everyone else does. As another comment pointed out, social events are organised as a part of facebook events, or through group chat. Buying and selling things locally are done through facebook groups rather than a newspaper or even eBay or CraigsList. Photos and the like are shared on social media for key important events in people's lives that you mightn't have the opportunity to see all that often.
All of these things can be worked around, but the alternatives are slower paced and less efficient and leave you ultimately out of the loop. So it's not a problem of imagination, it's a problem of wanting to be able to keep up with what's going on.
